The AlternatorGenerator, 48V Battery Charging

I bought a 12V car alternator off of craigslist for $100.  I wasn't looking for any specific model, but I wanted a serpentine pulley on the alternator, and it had to look decent.  Next was a Predator gas engine from Harbor Freight.  In this case, I purchased the 224cc MAX engine, which is 6.6hp.  The 212cc 6.5hp engine would have also worked well for this build.  

The goal is to make a dedicated generator that can recharge my 48V battery bank.  I'm using the EG4 LiFePO4 batteries, which is a little more than 30kWh.  Sometimes, during the winter, the solar production doesn't keep up with my loads.  That's when I need to supplement my solar with some generator run-time in order to recharge my battery bank.  Yes, 48V generators exist on the market, but they are thousands of dollars.  I built this generator for about $400.
